The Prime Minister has announced what he says is the most significant reform of Australia's intelligence and security arrangements in four decades.

Eliot Higgins is hardly a household name but he has something akin to legend-status among families of the 298 people killed when Malaysia Airlines flight 17 was blown out of the sky over Ukraine three years ago. Higgins online investigation network was the first to discover Russian military assets and troops were involved. And ever since he's been working closely with the official joint investigation team to track and identify key suspects.
